I need to find a way to reset this printer back to orginal settings. I have an error that will not go away. Any help or manuals are appreciated. I have all the normal documents. Getting rid of this error is a bit more advanced than what consumers can usually do. I have replaced all the parts, but the error is still there. I am looking for technical documentation!!

NEED REPAIR AND SERVICE MANUAL WITH ELECTRICAL CIRCUIT SYSTEM DIAGRAM FOR DO IT YOURSELF REPAIR AND SOME TIPS.
PROBLEM: STERO RECEIVER BLOWS 7A, 120V FUSE LOCATED NEXT TO POWER INCOMING LINE
WOULD APPRECIATE HELP
REGARDS TO ALL OF YOU
